    Five Step Process of

    Job Hazard Analysis

    Welcome!

    Introductions

    What do you know about Job Hazard Analysis

    (JHAs) ?

    Does OSHA require JHAs?

    Does a Client, GC, Corp. of Engineers

    require one?

    Where does it say so?

    Goals

    Given the information and exercises in

    this workshop, you will be able to:

    Explain to others why JHAs are important

    Recognize how the JHA can be a valuable

    planning, production, profit and safety tool.

    Know the five-step process and complete a

    JHA

    Activity

    Workers in their first year with their

    employer account for more than 50% of

    disabling claims.

    Why? Possible explanations

    JSA Purpose

    Effective JHAs help the employer

    recognize and control hazards and

    exposures in the workplace.

    How might the

    employees perception of

    a hazard differ from

    that of the employer or

    supervisor?

  • 1/9/2013

    4

    Activity

    Why is a JHA more effective than

    walk-around inspections in

    reducing accidents in the

    workplace?

    Probability

    Probability is defined as: the chance that

    a given event will occur.

  • 1/9/2013

    5

    Probability

    We can determine the safety probability

    based on the following:

    The number of employees exposed;

    The frequency and duration of exposure;

    The proximity of employees to the danger

    zone;

    Probability

    We can determine the safety probability

    based on the following:

    Factors which require work under stress;

    Lack of proper training and supervision or

    improper workplace design; or

    Other factors which may significantly

    influence the degree of probability of an

    accident occurring.

  • 1/9/2013

    6

    Probability

    Rating The probability rating is:

    Low - If the factors considered indicate it

    would be unlikely that an accident could

    occur;

    Medium - If the factors considered indicate it

    would be likely that an accident could occur;

    or

    High - If the factors considered indicate it

    would be very likely that an accident could

    occur.

    Severity

    The degree of injury

    or illness which is

    reasonably

    predictable.

  • 1/9/2013

    7

    Severity

    The severity is based on the following

    schedule:

    Other Than Serious - Conditions that could

    cause injury or illness to employees but

    would not include serious physical harm.

    (first aid for example)

    Serious Physical Harm - (example: all

    recordable injuries and illnesses)

    Activity

    Picking Apples:

    There are 20 workers picking apples.

    The orchard is made up of 400 trees.

    The workers are paid based on how much each one of them picks.

    Well-maintained equipment is provided but there is no training. The owner or the foreman will be in the general area most of the time.

    JHA Step 3

    Step Three - Describe the hazards in

    each step of the task.

    One of the primary purposes of the JHA is

    to make the job safer.

    The information gathered in this step will

    be valuable in helping to eliminate and/or

    reduce hazards associated with the job,

    and improve the system weaknesses that

    produced them.

    Contact-with: A person comes in contact with a harmful substance

    or material. The person initiates the contact.

    Caught-on: A person or part of his/her clothing or equipment is

    caught on an object that is either moving or stationary. This may cause the person to lose his/her balance and fall, be pulled into a machine, or suffer some other harm.

    caught in an opening or enclosure.

    Accident Types

    of the body or assumption of a strained or unnatural

    body position. A leading source of injury.

    Over-exposure:

    Over a period of time, a person is exposed to harmful

    energy (noise, heat), lack of energy (cold), or
